DCT700 suddenly S0a00 error, no picture on all channels, 2 days in a row

two days in a row now (yesterday afternoon and first thing this morning) I turn on my DCT700 SD terminal and find that ALL channels have no picture and instead display the S0a00 error message "One moment please, This channel should be available shortly".

meanwhile the channels on all my other TVs (DCX3500, DCX3200. DCT6200) are all fine

a quick power cycle of the DCT700 immediately restored all channels, although of course the guide data was empty and had to reload. So I had to power cycle it yesterday and again this morning.

Good thing I'm quite used to power cycling my other new Shaw equipment regularly. perhaps the DCT700 is feeling left out of all the fun and attention...

this DCT700 has worked flawlessly since I got it a few months ago (unlike the 3200 & 3510 !)

after posting above message, my DCT700 has been fine the past 4 days. no more S0a00 error...

but this morning, I turned on the TV and although there is picture on all channels, when I bring up the guide ALL channels show "to be announced". It was all fine last time I checked it yesterday, the guide data was all there.

meanwhile I checked my 3200, 3510, and 6200 and they all have good guide data

as mentioned in my original post, the DCT700 has otherwise been working without these problems since first installed a few months ago (please don't bother telling me to make sure the coax cable is screwed on tightly)

That does sound like a possible signal issue. Have you checked for/bypassed any splitters in place by this point? Let us know if it's still showing To Be Announced for all channels and we can follow up with you.

Yes, my DCT700 is still showing "to be announced" on all channels in the guide, now for two full days.

(Although moments before noticing your message I power cycled it, just in case that might force the guide to reload)

there are NO splitters in the feed going from the cable drop to the house and the DCT700.

In fact, there's only one splitter inside my whole house, and that's between my 3510 and 6200, on a totally different cable run. I did try unscrewing/re-attaching the cable to make sure it is firmly attached to the terminal and it seems fine.

is a "signal issue" the ONLY possibility for this kind of guide problem? I'm unclear why the problem should develop suddenly after several months, with no change to my installation.

btw earlier this week there seemed to be a number of similar reports from other people in the forum. surely it's not coincidental that so many suddenly developed "signal issues" ??

Thanks for the update. No, it's not necessarily a signal issue, but it's possible the frequency on which the guide information is carried is affected, possibly along with some other channels (which you might or might not get). It could be a software issue too though. I'll send you a message so I can see what we can do from our end. Check your inbox at the top.
